IME:
I like the bamboo contrast to the black leather (I have a Gucci black BTH but the body is woven like a basket with the bamboo handles) that looks fine in the summer even though it's black.
That shade of pink is very special. I have the same colour Gucci interlocking. Love it for a 'pop'.
From what you already have I'd say go for the 'special' pink but only if bright pink is something that's very you anyway. If you're a quieter person and find you never reach for your brighter coloured go for the classic black as the bamboo shopper mini in black you can use all year round anyway.
Can't wait to see which you end up with, you'll have to let us see when you get it
